I built a system :srsUE+zmq+srsRAN5G+open5gs，ran this network, according to the manual:
https://docs.srsran.com/projects/project/en/latest/user_manuals/source/outputs.html
I tried to decode the data from /tmp/gnb_mac.pcap and /tmp/ue_mac_nr.pcap by wireshark.
But I have sth wrong when I analyzed a MAC-layer PCAP using Wireshark.
As it said,
1、 Go to Edit->Preferences->Protocols->DLT_USER->Edit and add an entry with DLT=149 and Payload protocol=udp.
2、 Go to Analyze->Enabled Protocols->MAC-NR and enable mac_nr_udp
I got this result:
...
4 0.300681 UDP 340 48879 → 57005 Len=332 [ILLEGAL CHECKSUM (0)]
5 0.455932 UDP 559 48879 → 57005 Len=551 [ILLEGAL CHECKSUM (0)]
...
So ,what's the "ILLEGAL CHECKSUM"?How can I deal with it?
Thx!!
